Evans Carbon Project

Evans Carbon Project is a soil carbon sequestration project located in the Clarence Valley region of New South Wales. The project is situated near the locality of Cowper, approximately 20km northeast of the major regional centre of Grafton. Registered in July 2022, the project covers a project area of roughly 115 hectares on land primarily used for grazing.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models (2021) methodology. This method requires landholders to implement new management activities, such as altering stocking rates, improving pasture species, or modifying irrigation, to increase the amount of carbon stored in the soil. To generate credits, the proponent must demonstrate a measurable increase in Soil Organic Carbon (SOC) stocks over time compared to a baseline, verified through physical soil sampling and modelling.

Environmentally, the Cowper area lies within a high-rainfall, subtropical zone typical of the NSW North Coast. The site is located on the floodplain of the Clarence River, where soils are generally comprised of fertile alluvial types, such as Vertosols (cracking clays) or potentially sodic Kurosols, which are common in the Clarence-Moreton bioregion. These heavy soils are well-suited to holding carbon but require careful management to prevent compaction and erosion. The project is managed by Agriprove, a major Australian soil carbon developer, and focuses on grazing management strategies to enhance vegetation cover and soil health.
